To all whom it may concern: N

Be it known that I, Aoeiis'r T. Kmnmn, a citizen of the United States of Am rica, 'esiding at Detroit, in the county of W'ayne and State of Michigan have invented cer tain new and useful Improvements in Car- Doors, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to railway car'doors, and it is the principal object of the invention to obtain a more closely fitting and weather-proof construction. In the present state of the art railway freight cars are usually provided with sliding doorswhieh are supported on trollev hangers and when opened are slid in parallelism with the side of the car. In closed position such doors are intended to overlap and bear upon the sides of the door-opening but in praetice they frequently fail to form a weatherproof joint. W'ith improved construction a break-joint weathering is proi ided at the edges of the door without interfering with the sliding movement thereof, thereby rendering the strnetlire more weather-proof. Another feature of the construction is the means employed for locking and unlocking the door as hereinafter set forth.

In the drawings:

Figure 1 is a side elevation of a portion of the car to which my improved door is applied;

Fig. 2 is a cross section through the door in closed position;

Fig. 3 is a similar view after the door has been partly opened; and

Figs. 4 and 5 are horizontal sections showing the door in closed and partly opened position.

A is the sill of the car, B the siding, C the door-opening and D the door. Instead of arranging the door D to overlap the siding as is usual it is seated on a rabbeted bearing in the plane of the inner faceof the siding andouter face of thesill, This forms a break-joint which is rendered more effective by a tongue and groove engagement at opposite edges of the door, As shown, the forward edge of the door has a tongue E thereon, preferably formed by a flange of a Z-har E which constitutes a facing for the edge of the door. a groove F in the angle of the rabbet' while at the opposite .edge of the door is a tongue G engaging a groove H formed by a metal- This tongue E engages lio facing strip I. Siiflioient clearance is provided for movement of the door upon its seat so as to disengage the tongue E from the groove F, but the tongue G is of greater length so as to remain in engagenent with the groove H while the tongue E is also engaged with the groove F, as shown in Fig. 4. v v

For supporting the door and moving the same to open position hangers J are provided, which have a traveling engagement upon the covered track K extending along the top of the door-opening and adjacent siding. Inasmuch, however, as the plane of the door when seatedis inside of the plane in which it must travel to cl ar the Siding provision must be made for a lateral moveinent, whioh I accomplish by forming the hangers J in two parts J and J The part J enga es the track 1K and has an antifrictionroll L and a flange L'respectively inside and outside of the track to hold the section in the saline vertial plane,- also a roll L for su' ertingihe hanger on the track. The section J 2 is slidably secured to the section Jfso as to move transversely of the plane of the door. Ihis permits of moving the door laterally outward from the plane of its seat to a position where it will clear the siding of the car.

To facilitate adjustment of the door while against its seat to engage or disengage the tongue Eand groove F, I have provided a lever mechanism which as shown comprises a lever M pivoted to the inner side of the door and extending downward beneath the same. The Upper end of this lever is attached to a horizontal rod N which extends the width of the door and is adapted to bear against the opposite sides of the opening. Thus when the leverM is moved in one direction the rod N will bear against one side of the door frame, acting as a fulcrum for the lever in adjusting the door laterally. The reverse increment will be effected by operating the lever M in the opposite direc tion and in this way the door may be shifted for engaging or disengaging the tongue E. Lateral movement of the door iipon its hangers is facilitated by relieving the weight, and forthis purpose a lifting handle O is secured near the bottom. This handle isalso used-for operating a verticallyextending rod P, the lower end of which constitutes a locking bolt for the door in closed position, while the upper end carries a roll Q engaging the inclined top K of the track K. "he purpose of this latter construction is to facilitate the inward movement of the top of the door, which is accomplished by the rolling of the roll Q along the incline K whenever upward pressure is exerted on the handle 0. Thus the lifting of said handle, which relieves the Weight of the door from said hangers, also has the eff ct of moving the door laterally inward against its seat in position for engagement of the tongue E with the groove F.

To hold the door from contact with the siding B when moved in parallelism therewith wear-strips It are arranged along the path of movement. The ends of these strips are provided with hooks R which engage with the tongue E and hold the door from being drawn off its track. For locking the door I preferably arrange a hasp S which is pivoted at S to the siding and overlaps the inner edge of the door, engaging a staple T thereon. This hasp is preferably provided with an inwardly-extending lug U engaging an aperture in the metallic strip I so as to relieve stress from the hinges of the l1asp. The hasp also is provided with an angle-bend V engaging the edge of the door and holding the same from shifting.

In use, when the door is closed it forms a very effective weather-proof joint, and furthermore it does not project as far beyond the siding as in the usual construction. On the other hand, the door may be readily opened by first moving the lever M to disengage the groove from the tongue F and then lifting on the handle 0 and drawing the door outward and finally sliding it upon the track into parallelism with the siding of the car.

\Vhat I claim as my invention is 1. The combination with a car door, ofa recessed seat for said door, tongues upon opposite sides of said door for engaging grooves in the seat, the tongue on one side being longer than that on the other, means mounted on the door and adapted to engage either of the sides of the door opening for shifting the same to engage or disengage the shorter tongue, a hanger for supporting said door permitting of lateral movement thereof out of the plane of the recess, and a track on which said hanger travels along the side of the car.

2. The combination with a car door, of a recessed seat for said door, tongues upon opposite sides of said door for engaging grooves in said seat, the tongue on one side being shorter than that on the other and sufficient clearance being provided for the disengagement of the shorter tongue, means mounted on the door and adapted to engage either of the sides of the door opening for adjusting the same to engage and disengage said tongue, a hanger for supporting said doorpermitting of lateral movement thereof, and a track on which said hanger travels.

3. The combination with a car door, of a seat for said door, means for Supporting said door permitting of lateral adjustment into and out from said recess, a track for carrying said supporting means provided with an inclined covering, and means adapted to engage with said inclined covering for facilitating the lateral adjustment into said recess. 7

4. The combination with a car door, of a seat therefor, means for supporting said door permitting of lateral adjustment into and out from said seat, a track for carrying said supporting means provided with an inclined covering, a lifting handle for said door, and means carried by said lifting handle adapted to engage said inclined covering for facilitating later adjustment of the door into said seat and adapted to lock said door when adjusted inwardly.

5. The combination with a car door, of a V recessed seat for said door, tongues upon opposite sides of said door for engaging grooves in the seat, a hanger for supporting said door permitting of lateral movement thereof out of the plane of the recess, a track on which said hanger travels along the side of the car, a lever pivoted to the inner side of the door and extending downward beneath the same, and a substantially horizontal rod secured to said lever adapted to bear against either of the opposite sides of the door opening to movesaid door.

6. The combination with a car door, of a seat for said door, means for supporting said door permitting of adjustment into and out from said seat, a track for carrying said supporting means provided with an inclined portion.v and means adapted to engage said inclined portion of the track for facilitating the adjustment of the door into its seat.

7. The combination with a car door, of a seat therefor, a hanger for supporting said door permitting of movement into and out from said seat, a rod of substantially the width of said door and carried thereby, adapted to be moved in opposite directions to bear against either of the sides of the door opening tomove said door in the opposite directions, and means for actuating said rod.

In testimony whereof I atfix my signature.
